PAINT-OIL.

SPECIFICATION forming part of Letters Patent No. 568,419, datedSeptember 29, 1896. Application filed December 27, 1895. fierial No.573,458. (No specimens.)

To all whom it may concern:

Be it known that I, IRVING H. SWINK, a citizen of the United States,residing at Dublin, in the county of Bucks and State of Pennsylvania,have invented certain new and useful Improvements in Paint-Vehicles, ofwhich the following is a specification.

The invention relates to improvements in composition of paint oils orvehicles.

The object of the present invention is to provide the means forproducing a very durable, adhesive, and absolutely waterproof paintvehicle or oil that can be manufactured very cheaply compared with otherpaintoil for house or oil paints, said paint-oil requiring no dryingmaterial to be added to dry the same, namely, such as turpentine orbenzin, which impair the wearing qualities of the paint when exposed tothe'weather. This oil will impart a gloss to the paint not to beobtained by any other oil.

One of the chief objects of my invention is to take cows milk after thebutter-fat has been extracted by a separator but otherwise in itsnatural state, and by the addition of rosin or a resinous gum, sulfur orbrimstone, and kerosene-oil in the proper manner and suitableproportions to convert it into a paint vehicle or oil.

Another object of my invention is to provide a paint vehicle or oil withunusual gloss by adding to milk sufficient rosin or resinous gum tosecure the desired amount of gloss and adhesiveness, then adding sulfuror brimstone as a drier and to overcome the susceptibility of the rosintosoften up by the application of heat or the rays of the sun. Thesulfur or brimstone also helps to create the desired gloss.

My paint oil or vehicle is susceptible of being thinned to any desiredconsistency with linseed-oil.

My aforesaid oil contafins the following ingredients, namely: rosin,sulfur, milk, and deodorized kerosene-oil. The method or process ofcompounding or manufacturing said oil is as follows, viz: I take equalparts of rosin and sulfur and melt the same together by heat, and whenyet hot I introduce into the mass equal quantities of milk anddeodorized kerosene-oil until the desired consistency is obtained. comescold, run the same through apaintmill, so as to thoroughly incorporatethe ingredients, as the heat causes the casein to separate from theother properties of the milk.

Changes in the proportion and the minor details of compounding or themanufacturing of said oil may be resorted to without departing from theprinciple or sacrificing any of the advantages of this invention.

Having thus fully described my invent-ion, what I claim as new anduseful is- 1. The hereinbefore-described paint-vehicle consisting ofrosin, sulfur, milk, and deodorized kerosene-oil, in the proportionssubstantially as described.

2. The herein-described process of converting milk into a paint vehicleor oil, by the addition of rosin, sulfur, and kerosene-oil,substantially as described.

3. The herein-described process of converting milk from which thebutter-fat has been extracted by a separator, but otherwise in itsnatural state, into a paint-vehicle by combining with it aresinous andsulfurous compound and kerosene-oil, substantially as described.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.
